DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a web roll wrapping apparatus for automatically wrapping the outer circumference of a wound web roll.

[0002]

2. Description of the Related Art Conventionally, in obtaining a narrow web such as paper or plastic film, a wide web, which is a raw material, is slit in the length direction of the web, and a plurality of narrow webs slit to a required width dimension. Each width web is wound around each of a plurality of winding shafts mounted on a pair of winding rollers, and the product is taken out of the slitter device as a web roll. At this time, if the end of the wound web roll is still in the wound state,
During handling such as transporting the web roll, the narrow web is unwound or displaced in the width direction, resulting in a poor winding appearance. Therefore, a terminal fixing process for fixing the terminal using an adhesive tape or the like is usually performed. However,
When the adhesive tape is directly applied to the outer peripheral surface of the web roll and subjected to terminal treatment, the adhesive tape is easily peeled off when the adhesive strength is weak, and the web roll is used when the adhesive strength is too strong. In such a case, it becomes difficult to remove the adhesive tape, or a part of the end of the web roll to which the adhesive tape is stuck is cut off, the form of the web roll is damaged, and the loss that the damaged part is cut off is lost. There were inconveniences such as occurrence.

[0003] In addition, a product obtained by simply applying an adhesive tape to the end of a web roll and terminating the end of the web roll has a problem that the surface of the web is damaged or stained because the web is exposed to the outside. And the commercial value is reduced. Therefore, the web roll that has been subjected to terminal treatment with an adhesive tape is often re-wrapped with wrapping paper or the like. However, such body-wrapping is inefficient because, for example, the wound web roll is taken out of the slitter device and manually performed, and attempts to put the web rolls taken out of the slitter device one by one on an automatic body-wrapping device are made. However, there is a problem that the packaging work is performed in a separate process, which leads to an increase in cost and is not economical, and the terminal treatment of a plurality of web rolls and the body packaging are simultaneously performed in the winding process. Technology has not yet been found.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a body winding tape is automatically supplied during a winding process without directly applying an adhesive tape to a slitted and wound web roll. An object of the present invention is to provide a web roll body-wrapping apparatus capable of producing a product web roll which is easy to handle when used, has little product loss, is excellent in aesthetic appearance, and is economical.
